Description

Technical Field

[0001] The present disclosure relates to the technical field of fracture fixation equipment, and in particular to a fracture splint. Background Art

[0002] At present, the medical equipment and treatment methods widely used in fracture injuries include: the plaster fixation method which uses medical gypsum powder (non-crystalline powder formed by crushing, heating and dehydrating natural calcium sulfate stone) and absorbent bandage to wrap the injured limb for fixation; the thermoplastic splint fixation method which uses special synthetic polymer polyester material to fix the injured limb after being soaked in hot water; the roll splint fixation method which uses splints made by cutting large pieces of IXPE (polyethylene cross-linked foam plastic) boards containing aluminum plates on site; the negative pressure splint fixation method which uses the difference between the inner and outer layers of material and a self-closing air cylinder to suck the internal gas of the product so that the polymer particles mixed between the inner and outer materials are rubbed into shape and hardened to achieve the fixation effect; and the traditional Chinese medicine small splint fixation method which uses tough wood to fix the injury over a short distance.

[0003] In the current use of fracture fixation devices, the problems of mainstream standard splints are concentrated in the fact that the overall operation takes a long time and has high technical requirements for the operator; the single splint has a relatively fixed shape and poor adaptability to different limb parts; and the existing fracture splints on the market are closed and fixed in shape, making it difficult to observe the wound status and long-term closure can easily cause bacteria to grow and cause additional diseases, which is not conducive to the timely follow-up of subsequent medical treatment in disaster emergencies; a large number of medical auxiliary equipment are required to cooperate in several aspects of injured limb fixation.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of this application without substantial change in the technical content.

[0036] The present disclosure provides a fracture splint. The structure of the fracture splint is shown in FIG. Figure 1 to Figure 4 , comprising a splint body 1 and a fixing member 2;

[0037] The splint body 1 comprises a support layer 11 made of a tough material and a buffer layer 12 fixed and covered on one side of the support layer 11 by bonding. The splint body 1 is divided into a long limb area A, a short limb area B and a bending area C connected between the long limb area A and the short limb area B and formed by the toughness of the material itself along the length direction of the splint body 1. The bending area C enables the fracture splint to be in two use states. In the first use state, the axes of the long limb area A and the short limb area B coincide. In the second use state, the axes of the long limb area A and the short limb area B are perpendicular. Two folds are also provided on the splint body 1 along its length direction, so that the splint body has a U-shaped cross section when folded along the folds; The main body of the splint in the long limb area A is divided into a first main board A1 and a first guard plate A2, the main body of the splint in the short limb area B is divided into a second main board B1 and a second guard plate B2, and the main body of the splint in the bending area C is divided into a third main board C1 and a third guard plate C2 through a hollow design, and the first main board A1 and the first guard plate A2 are connected through a buffer layer 12, and a plurality of openings are provided on the first main board A1. When the main boards and the corresponding guard plates in the long limb area A and the short limb area B are in use, they are located on different sides of the injured limb, and the third main board and the third guard plate in the bending area C are located on the same side of the injured limb when the fracture splint is in use state one, and on different sides of the injured limb joint when the fracture splint is in use state two;

[0038] The fixing part 2 includes a first strap 21 arranged in the long limb area A and a second strap 22 arranged in the bending area C, which are used to wrap the injured limb and fix the injured limb; the buckles 23 and 24 arranged at each opening on the first main board A1 are used to open or close the corresponding openings on the first main board A1.

[0039] In some embodiments, the fracture splint can achieve accurate, rapid, and stable fracture fixation of injured limbs in different parts of the patient's body, and during the fixation process, the movement of the injured limb is reduced as much as possible, thereby effectively avoiding the problem of secondary injury to the patient during the medical treatment process. Through the morphological change of the bending zone C in the fracture splint, the splint body 1 can be in a 180° straight line form (i.e., use state one) and a 90° bending form (i.e., use state two), corresponding to multiple comprehensive fractures of the whole leg and arm and half-limb fractures such as the calf, forearm, and upper arm. The outer contour of the splint body 1 in the flat state is a rectangle with a size of 70cm×30cm. The long limb area A accounts for about 2 / 3 of the overall length of the splint body 1, and the short limb area C and the bending area C account for about 1 / 3 of the overall length of the splint body 1.

[0040] In some embodiments, the tough material constituting the outer support layer 11 of the splint body 1 can be PP material or other tough plastic material, and is manufactured by existing mold opening and injection molding methods. Optionally, reinforcing ribs are partially provided on the support layer 11 to increase the toughness of the support layer 11.

[0041] In some embodiments, the buffer layer 12 constituting the inner side of the splint body 1 (i.e., the side in contact with the injured limb) can be made of flexible materials such as soft glue, dense foam board, sponge, etc., and the specific shape is determined by washing and extruding the flexible material (both are existing processes).

[0042] In some embodiments, the first guard plate A2 located in the long limb area A is a square with chamfers, which is used to help fix the injured long limb. The first guard plate A2 is a part of the splint body 1, and is integrally formed with the outer support layer 11 and the inner buffer layer 12. The partitioning and fixing functions of the guard plate and the main board are achieved through bending through the hollow design and the toughness of the material itself. The first hole A3 is formed between the first main board A1 and the first guard plate A2 through hollowing out, which is convenient for observing the healing of the injured limb. It should be noted that, since the first guard plate A2 needs to be bulged inward when the fracture splint is in use, the first main board A1 and the first guard plate A2 are located on different sides of the injured limb. Specifically, the first guard plate A2 is located on the front side of the injured limb, and the first main board A1 is located on the left, right and back sides of the injured limb, thereby wrapping the injured limb in all directions. At this time, the inner and outer sides of the first guard plate A2 are transformed. In order to ensure the skin-friendliness of the side of the first guard plate A2 in contact with the injured limb, a buffer layer 12 is set in the area where the first guard plate A2 contacts the injured limb, that is, when the first main board A1 and the first guard plate A2 are in an initial state on the same plane, the buffer layer 12 thereon is located on different sides of the support layer 11.

[0043] In some embodiments, the second guard plate B2 and the third guard plate C2 in the short limb area B and the bending area C are also integrally formed with the support layer 11 and the buffer layer 12 of each area, and the partitioning and fixing functions of the guard plate and the main plate are realized by bending through the hollow design and the toughness of the material itself. The second guard plate B2 is used to help fix the short-end injured limb, or together with the long limb area A, help fix the whole leg and the whole arm. The third guard plate C2 is used to help fix the wrist / elbow joint, or together with the long limb area A and the short limb area B, help fix the whole leg and the whole arm. The guard plate body of the short limb area B is divided into the second main plate B1, the second guard plate B2 and the second hole B3 through the hollow design, and the guard plate body of the bending area C is divided into the third main plate C1, the third guard plate C2 and the third hole C3. The difference from the first guard plate A2 in the long limb area A is that the second guard plate B2 and the third guard plate C2 are both strip-shaped. Since the second guard plate B2 and the third guard plate C2 have a smaller area and do not directly contact the injured limb, no buffer layer 12 is set on the second guard plate B2 and the third guard plate C2.

[0044] In some embodiments, the first strap 21 and the second strap 22 in the fixing member 2 are connected to the splint body 1 by inserting the corresponding holes 13 and 14 on the side of the splint body 1, and the tail end of each strap is provided with a buckle or Velcro to fix the head and tail of the strap when in use. Each strap can be made of common clothing materials such as cotton and linen that are skin-friendly and have a certain degree of durability through existing weaving, textile and other processes. The buckle parts 23 and 24 are arranged on the left or right side of the outer side of the support layer 11 at the opening on the first main board A1, and the buckle parts 23 and 24 can be selected as a lock buckle or a buckle. When it is necessary to fix the fracture of the injured person, first make the first guard plate A2 and the second guard plate B2 protrude toward the inner side of the splint body 1, and set the third guard plate C3 to protrude toward the inner side of the splint body 1 or maintain the same plane with the third main board C1 as needed, unlock the fasteners 23 and 24, so that the first main board A1 is disconnected at the opening, and then the fracture splint is moved toward the injured limb from the side of the protruding direction of the guard plate until it contacts the injured limb and wraps the front and left and right sides of the injured limb. The first main board (in the shape of a strip) at the opening passes through the gap between the injured limb and the plane below it to be located at the back of the injured limb, and then the first strap 21 and the second strap 22 are used to fix the splint body 1 to the injured limb. Finally, the fasteners 23 and 24 are locked to close the first main board located at the back of the injured limb at the opening to wrap the back of the injured limb. Furthermore, the fixing member 2 further includes four connecting members 25 and 26 located on the inner and outer sides of the bending area C and the short limb area B. When the fracture splint is in the second use state, the bending area C and the short limb area B have an overlapping portion, so the connecting members 25 and 26 are used to tightly connect the overlapping portion of the bending area C and the short limb area B to ensure the fixation of the injured limb in the overlapping portion. The connecting members 25 and 26 can be in the form of Velcro or snaps.

[0045] The method of using the fracture splint of this embodiment is described as follows according to different usage states of the fracture splint:

[0046] See also Figure 5 , for large-scale limb fractures, the method of using the fracture splint in a 180-degree folded state, i.e., the first use state, includes the following steps:

[0047] Step 1: Fold both sides of the plywood body 1 along the creases at 90 degrees toward the inner buffer layer 12, and standardize the positions of the first guard plate A2 and the second guard plate B2 so that they are in an inwardly protruding state, and keep the third guard plate C2 consistent with other parts of the main board;

[0048] Step 2: Unlock the fasteners 23 and 24 on the first main board A1, so that the first main board A1 is disconnected at the opening, visually check the positional relationship between the lowermost opening on the first main board A1 and the lowermost end of the injured limb, and ensure that the lowermost end of the injured limb should be located above the lowermost opening on the first main board, and move the fracture splint toward the injured limb from the side of the protruding direction of the first and second guard plates until the long limb area A contacts the injured limb and forms a wrap around the front and left and right sides of the injured limb, then pull the fracture splint upward along the direction of the injured limb, so that the lower end of the injured limb passes through the bending area C and the short limb area B in sequence until it reaches the designated position, at which time the first guard plate A2 and the second guard plate B2 are located on the front side of the injured limb, forming an effective wrap around the front side of the injured limb, and the third guard plate C2 is located on the back side of the injured limb, so as to fix the back side of the injured limb, and then lock the fasteners 23 and 24, so that the first main board A1 located on the back side of the injured limb is closed at the opening, forming a wrap around the back side of the injured limb;

[0049] Step three: After the guard plate body is placed, fix the first strap 21 located in the long limb area A and the second strap 22 located in the bending area C to the guard plate body respectively. Specifically, pass the first strap 21 located on the outside of the first main board A1 through the hole 13, and the second strap 22 through the hole 15. Fasten them tightly and adjust the tightness to fix the front side of the injured limb, thereby completing the fixation of the injured limb.

[0050] See also Figure 6 For small-scale limb fractures, the method of using the fracture splint in the 90-degree folded state, i.e., the second use state, includes the following steps:

[0051] Step 1: Fold both sides of the splint body 1 along the creases at 90 degrees toward the inner buffer layer 12, and at the same time standardize the positions of the first guard plate A2, the second guard plate B2, and the third guard plate C2 so that they are in an inwardly protruding state;

[0052] Step 2: Fold the bending area 90 degrees toward the bending direction of the limb joint, so that the inner and outer connecting pieces 25 and 26 on both sides are connected to each other;

[0053] Step 3: Unlock the fasteners 23 and 24 on the first main board A1, disconnect the first main board A1 at the opening, visually observe the positional relationship between the injured limb and the fracture splint, so that the long limb area, short limb area and joint area of ​​the injured limb correspond to the long limb area A, short limb area B and bending area C respectively, and move the fracture splint toward the injured limb from the side of the protrusion direction of each guard plate until it contacts the injured limb and forms a wrap around the front side and left and right sides of the injured limb. At this time, the first, second and third guard plates should all be on the front side of the injured limb, and then lock the fasteners 23 and 24 to close the first main board A1 located on the back side of the injured limb at the opening, so as to form an effective wrap around the front side of the injured limb;

[0054] Step 4: After the guard plate body is placed, the first strap 21 located in the long limb area A and the second strap 22 located in the bending area C are fixed to the guard plate body respectively, thereby completing the fixation of the injured limb.

[0055] To sum up, the present invention adopts the advantages of traditional Chinese medicine fracture splints, combines with the human body structure, and designs a fracture splint with certain elasticity, which can be folded repeatedly and is suitable for use at multiple points on the limbs. Compared with the existing technology, this splint provides an innovative comprehensive first aid fracture splint that is more suitable for emergency fracture rescue in terms of actual medical treatment effectiveness, has the characteristics of simple and fast operation, accurate positioning of fracture points, obvious braking effect, convenient large-scale carrying, certain adjustability, can be operated by one person within 30 seconds, is not prone to complications or infections, and can effectively avoid secondary injuries during the medical process.
